The Download: The Pentagon’s new AI plans, and next-gen nuclear reactors


This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

The Pentagon is planning for AI companies to train on classified data, defense official says 

The Pentagon plans to set up secure environments for generative AI companies to train military-specific versions of their models on classified data, MIT Technology Review has learned.  

AI models like Anthropic’s Claude are already used to answer questions in classified settings, including for analyzing targets in Iran. But allowing them to train on and learn from classified data is a major new development that presents unique security risks.  

It would embed sensitive intelligence—like surveillance reports or battlefield assessments—into the models themselves. It would also bring AI firms closer to classified data than ever before. Read the full story

What do new nuclear reactors mean for waste? 

The way the world currently deals with nuclear waste is as creative as it is varied: drown it in water pools, encase it in steel, bury it hundreds of meters underground. But an approaching wave of new reactors could introduce fresh challenges to nuclear waste management.   
 
The new designs and materials could require some engineering solutions. And there’s a huge range of them coming, meaning there’s an equally wide range of potential waste types to handle. Read the full story

MIT Technology Review Narrated: how uncrewed narco subs could transform the Colombian drug trade 

For decades, handmade narco subs have been among the cocaine trade’s most elusive and productive workhorses, ferrying tons of drugs from Colombia to the rest of the world.  

Now off-the-shelf technology—Starlink terminals, plug-and-play nautical autopilots, high-resolution video cameras—may be advancing that cat-and-mouse game into a new phase. 

Uncrewed subs could move more cocaine over longer distances, and they wouldn’t put human smugglers at risk of capture. Law enforcement agencies are only just beginning to grapple with the consequences.

How the Pentagon is adapting to China’s technological rise 

It’s been just over a year since Kathleen Hicks stepped down as US deputy secretary of defense. 

As the highest-ranking woman in Pentagon history, Hicks shaped US military posture through an era defined by renewed competition between powerful countries and a scramble to modernize defense technology. 

In this conversation with MIT Technology Review, Hicks reflects on how the Pentagon is adapting—or failing to adapt—to a new era of geopolitical competition. She discusses China’s technological rise, the future of AI in warfare, and her signature initiative: Replicator. Read the full story

Do you ever walk past a person on the streets exhibiting mental health issues and wonder what happened to their family? I have a brother—or at least, I used to. I worry about where he is and hope he is safe. He hasn’t taken my call since 2014.

When I was 13, I had a very bad day. I was in the back of the car, and what I remember most was the world-crushing sound violently panging off every surface: he was pounding his fists into the steering wheel, and I worried it would break apart. He was screaming at me and my mother, and I remember the web of saliva and tears hanging over his mouth. His eyes were red, and I knew this day would change everything between us. My brother was sick.

Nearly 20 years later, I still have trouble thinking about him. By the time we realized he was mentally ill, he was no longer a minor. The police brought him to a facility for the standard 72-hour hold, where he was diagnosed with paranoid delusional schizophrenia. Concluding he was not a danger to himself or others, they released him.

There was only one problem: at 18, my brother told the facility he was not related to us and that we were imposters. When they let him out, he refused to come home.

My parents sought help and even arranged for medication, but he didn’t take it. Before long, he disappeared.

My brother’s decline and disappearance had nothing to do with the common narratives about drug use or criminal behavior. He was sick. By the time my family discovered his condition, he was already 18 and legally independent from our custody.

The last time he let me visit, I asked about his bed. I remember seeing his dirty mattress on the floor beside broken glass and garbage. I also asked about the laptop my parents had gifted him just a year earlier. He needed the money, he said—and he had maxed out my parents’ credit card.

In secret from my parents, I gave him all the cash I had saved. I just wanted him to be alright.

My parents and I tried texting and calling him; there was no response except the occasional text every few weeks. But weeks turned into months.

Before long, I was graduating from high school. I begged him to come. When I looked in the bleachers, he was nowhere to be seen. I couldn’t help but wonder what I had done wrong.

The last time I heard from him was over the phone in 2014. I tried to tell him about our parents and how much we all missed him. I asked him to be my brother again, but he cut me off, saying he was never my brother. After a pause, he admitted we could be friends. Making the toughest call of my life, I told him he was my brother—and if he ever remembers that, I’ll be there, ready for him to come back.

I’m now 32 years old. I often wonder how different our lives would have been if he had been diagnosed as a minor and received appropriate care. The laws in place do not help families in my situation.

My brother has no social media, and we suspect he traded his phone several years ago. My family has hired private investigators over the years, who have also worked with local police to try to track him down.

One private investigator’s report indicated an artist befriended my brother many years ago. When my mother tried contacting the artist, they said whatever happened between them was best left in the past and declined to respond. My mom had wanted to wish my brother a happy 30th birthday.

My brother grew up in a safe, middle-class home with two parents. He had no history of drug use or criminal record. He loved collecting vintage basketball cards, eating mint chocolate chip ice cream, and listening to Motown music. To my parents, there was no smoking gun indicating he needed help before it was too late.

The next time you think about a person screaming outside on the street, picture their families. We need policies and services that allow families to locate and support their loved ones living with mental illness, and stronger protections to ensure that individuals leaving facilities can transition into stable care. Current laws, including age-based consent rules, the limits of 72-hour holds, and the lack of step-down or supported housing options, leave too many families without resources when a serious diagnosis occurs.

Governments and lawmakers need to do better for people like my brother. As someone who thinks about him every day, I can tell you the burden is too heavy to carry alone.
